Packaging material / Disposal of old machine
2
Packaging material
The packaging material used protects
the machine during transportation.
Please retain the original box and
polystyrene pieces so that you can
pack the machine securely, should you
need to transport it in the future.
The original packaging should also be
kept in case the machine ever needs to
be returned to Miele for servicing.
Disposal of your old appliance
Electrical and electronic appliances
often contain valuable materials. They
also contain materials which, if handled
or disposed of incorrectly, could be
potentially hazardous to human health
and to the environment. They are,
however, essential for the correct
functioning of your appliance. Please
do not therefore dispose of it with your
household waste.
Please dispose of it at your local
community waste collection / recycling
centre or contact your Dealer for
advice.
Ensure that it presents no danger to
children while being stored for disposal.

Safety with children
Caution! Danger of burning and scalding on the dispensing

Children's skin is far more sensitive to high temperatures than that
of adults.
Ensure children do not touch hot surfaces of the coffee machine or
place parts of their body under the dispensing spouts.
 Install the coffee machine where it is out of the reach of children.
 Children under eight years of age must be kept away from the

Warning and Safety instructions

Technical safety
 A damaged coffee machine is dangerous. Check it for any visible
damage before setting it up. Never attempt to use a damaged coffee
machine.
 To avoid the risk of damage to the machine, make sure the
connection data (voltage and frequency) on the data plate
corresponds to the household supply, before connecting the
machine to the mains supply. Consult a qualified electrician if in any
doubt.
 The electrical safety of this coffee machine can only be
guaranteed when correctly earthed. It is essential that this standard
safety requirement is met. If in any doubt please have the electrical
installation tested by a qualified electrician.
 Reliable and safe operation of the coffee machine can only be
guaranteed if it is connected to the mains electrical supply.
 Do not connect the machine to the mains electricity supply by a
multi-socket adapter or an extension lead. These are a fire hazard
and do not guarantee the required safety of the appliance.
 The coffee machine must not be used in a non-stationary location
(e.g. on a ship).
 Unplug the machine from the power supply immediately if you
notice any damage or smell scorching, for example.
 Ensure that the mains connection cable cannot be pinched or
damaged by any sharp edges.
 The mains connection cable should not hang down. Someone
could trip over it with the risk of injury and damage the machine.
 Only use the coffee machine in rooms where the ambient
temperature is between +16°C and +38°C.

Warning and Safety instructions
11
 Do not place the coffee machine near a window in direct sunshine
or right next to an appliance that gives off heat. These would subject
the machine to ambient temperatures outside its permitted operating
range.
 Danger of overheating. Ensure that there is sufficient ventilation
around the coffee machine. Do not cover it with tea towels etc.
whilst it is in use.
 If the coffee machine is positioned behind a kitchen furniture door,
it may only be used with the furniture door open. This will prevent the
formation of heat and humidity and subsequent damage to the
machine and/or furniture unit. Do not close the furniture door while
the coffee machine is in use. Ensure the coffee machine has cooled
down completely before closing the furniture door.
 Protect the coffee machine from water and water spray. Do not
immerse the machine in water.
 Repairs and other work by unqualified persons to the machine
and the connection cable could be dangerous. The manufacturer
cannot be held liable for unauthorised work. Repairs may only be
carried out by a Miele authorised service technician.
 While the machine is under guarantee, repairs should only be
undertaken by a Miele authorised service technician. Otherwise the
guarantee is invalidated.
 Faulty components must only be replaced by genuine Miele
Original spare parts. The manufacturer can only guarantee the safety
of the machine when Miele replacement parts are used.
 The coffee machine must be disconnected from the electricity
supply during repair work.
 Never open the outer casing of the machine. Tampering with
electrical connections or components and mechanical parts is highly
dangerous to the user and can cause operational faults or electric
shock.

Warning and Safety instructions
12
 Disconnect the coffee machine from the power supply if it is not
going to be used for a while.
 Only use genuine original Miele accessories with this machine.
Using spare parts or accessories from other manufacturers will
invalidate the guarantee, and Miele cannot accept liability.

Warning and Safety instructions
13
Correct use
The spouts present a danger of burning or scalding.
The liquids and steam dispensed are very hot.
 Please note:
– Keep well away from the area underneath the spouts when hot
liquids and steam are being dispensed.
– Do not touch hot components.
– Hot liquid or steam could spatter from the spouts. Ensure that the
central spout is clean and fitted correctly.
– Water in the drip tray can also be very hot. Take care when
emptying it.
 Please note the following regarding water:
– Only use cold, fresh tap water to fill the water container. Hot or
warm water or other liquids could damage the coffee machine.
– Change the water every day to prevent a build-up of bacteria.
– Do not use mineral water. Mineral water will cause serious
limescale deposits to build up in your machine and damage it.
– Do not use water from a reverse osmosis unit in this machine.
This would damage it.
 Only fill the bean container with roasted espresso/coffee beans.
Do not fill the bean container with coffee beans which have been
treated with additives or with ground coffee.
Do not fill the bean container with any type of liquid.
 Do not use green (unroasted) coffee beans or mixtures of coffee
beans which contain green coffee beans. Green coffee beans are
very hard and still contain a certain amount of residual moisture.
These can damage the coffee machine grinder as soon as grinding
begins.

Warning and Safety instructions
14
 Do not use coffee beans which have been treated with caramel,
sugar or other substances including sugary liquids. Sugar will
damage the coffee machine.
 Only add ground coffee or the Miele cleaning tablets for
degreasing the brew unit to the ground coffee chute.
 Do not use any caramelised ready ground coffee. The sugar in the
coffee will stick to and block the brew unit of the coffee machine.
The cleaning tablets for degreasing the brew unit will not remove this
type of deposit.
 Only use milk without additives. Additives in milk usually contain
sugar and this will stick to the milk pipework.
 Do not place any alcohol mixtures which are alight underneath the
central spout. The flames could ignite plastic components and cause
them to melt.
 Do not use naked flames, e.g. a candle on or near the coffee
machine. The coffee machine could catch fire with the risk of the fire
spreading.
 The machine must not be used for cleaning objects.

Warning and Safety instructions
15
Cleaning and care
 Disconnect the coffee machine from the power supply before
cleaning.
 Clean the coffee machine and the milk flask (supplied as standard,
depending on model) daily, particularly before using for the first time
(see "Cleaning and care").
 All parts of the milk system need to be cleaned thoroughly and
regularly. Milk contains bacteria which proliferate rapidly with
inadequate cleaning.
 Do not use a steam cleaner to clean this machine. Steam could
reach electrical components and cause a short circuit.
 If you use hard water (>20°dH / 3.6 mmol/l) or if the coffee
machine is used intensively, it may be necessary to descale the
machine manually in addition to automatic descaling.
 If you are descaling the coffee machine manually, carry out
descaling regularly depending on the hardness level of your water.
Descale the machine more frequently if you use very hard water.
Miele cannot be held liable for damage arising from insufficient
descaling, the use of incorrect descaling agent or the use of
descaling agent which is not of the appropriate concentration.
 Degrease the brew unit regularly with Miele cleaning tablets.
Depending on the natural oil content of the coffee used, the brew
unit can become blocked quite quickly.
 Used coffee grounds should be disposed of with the organic
rubbish or on the compost heap. Do not empty them down the sink,
as they could block it.

Warning and Safety instructions
16
For machines with stainless steel surfaces:
 Do not use sticky notes, transparent adhesive tape, masking tape
or other types of adhesive on stainless steel surfaces. These
damage the surface, causing it to lose its dirt repellent protective
coating.
 The finish on stainless steel surfaces is susceptible to scratching.
Even magnets can cause scratching.
